The airline and operator on Friday (24 April) confirmed it had removed surcharge provision across all flights and holidays.
It follows a plea from Deben Travel owner Lee Hunt; writing for TTG on Friday, Hunt called on the UK's major travel businesses to support agents by offering reassurance on the prospect of fuel surcharging.
Surcharges could be use to cover various cost increases, such as rising fuel prices. Europe is currently facing a shortage of jet fuel owing to the war in the Middle East.
Jet2, though, has stressed that while these provisions exist, the company has never previously applied them.
The business said its decision came amid speculation some airlines and travel companies may introduce surcharges, and was an attempt "to put customers first".
"Today’s announcement means Jet2 has taken an industry-leading position by pledging not to pass such cost increases onto customers after they have booked," it said.
"This means customers booking with Jet2 can lock in their flight or holiday price with total confidence."
The policy applies to flights and holidays booked via all sales channels, including through travel agents. It does not apply to any tourist taxes levied on visitors, which are payable in destination to accommodation providers.
Steve Heapy, Jet2.com and Jet2holidays chief executive, said: “Holidaymakers should have every right to book their hard-earned break in the sun, without worrying about being hit with additional costs, and they can have that complete assurance when they book a flight or holiday with Jet2.
"As a result of today’s announcement, customers booking with Jet2 know that they are locking in their price without additional cost surprises later and we strongly believe that is the right thing to do by them.
"Ahead of a busy summer this is yet more evidence of why, on top of our incredible holidays and award-winning customer service, nothing beats a Jet2holiday."
